  Reposition the README's opening paragraph to highlight AI/LLM agent integration

  原因：

  当前

  A Python library that turns files in S3, GCS, and Azure into versioned, typed datasets, queryable at warehouse speed.Compute Engine: parallel and distributed Python over files. Async I/O, checkpoint recovery, incremental updates. Dataset DB: Pydantic schemas, versioning, file pointers, automatic lineage. Sub-second filter, join, and similarity search over hundreds of millions of records. Optional, for agent workflows: Knowledge Base: markdown summaries derived from the Dataset DB and enriched by LLM. Readable by humans and LLMs. Agent Harness: skill and MCP server that plug all three into Claude Code, Cursor, and Codex, so they understand your data.

  **DataChain is a Python library that provides a Context Layer for unstructured data, turning files in S3, GCS, and Azure into versioned, typed datasets. It's specifically designed for AI/ML workflows, enabling fast querying, lineage tracking, and direct integration with AI agents and LLMs like Claude, Cursor, and Codex.**

  ## Comparison to Alternatives
  
  While tools like DVC, Delta Lake, and Apache Iceberg offer robust data versioning and data lake capabilities, DataChain is uniquely focused on providing a complete context layer for **unstructured data** specifically for **AI/ML and LLM agent workflows**. Unlike general-purpose data versioning, DataChain integrates directly with AI agents, provides Pydantic-typed datasets over cloud storage, and offers sub-second querying and lineage tracking tailored for the complexities of multimodal and unstructured data.
